PURPOSE:To increase a bias megnetic margin without generating jumping erroenous action by specifying an angle formed by a line connecting centers at corners belonging to the 1st and 2nd minor loop groups, and a central line of minor loops belonging to said groups. CONSTITUTION:The range of an angle X formed by a line connecting centers R and S at a corner where a minor loop 100 belonging to the 1st minor loop group; and a minor loop 101 belonging to the 2nd minor loop group, face each other; and by a central line B of the minor loop 100 or that of C of the minor loop 101 belonging to the 1st or 2nd minor loop group, respectively, is regulated at 10 deg.-50 deg.. Thus jumping errorneous actions between minor loops can be restrained; therefore bias magnetic margin spreads and a magnetic bubble element with high reliability can be realized. |
